Cygwin: mmap: fix protection when unused pages are recycled
Previously, when unused pages from an mmap_record were recycled, they
were given the protection of the mmap_record rather than the
protection requested in the mmap call. Fix this by adding a
"new_prot" parameter to mmap_list::try_map() and
mmap_record::map_pages() to keep track of the requested protection.
Then use new_prot in the calls to VirtualProtect().
